ADJUSTABLE MIRROR FOR BOILERS.

Specification of Letters Patent.

Patented June 25, 1918.

Application led November 5, 1917. Serial No. 200,410.

To all whom z't may concern:

Be it known that GEORGE F. KNOLLMANN, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, has invented certain new and useful Improvements in Adjustable Mirrors for Boilers; and he does hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in adjustable mirrors for use in connection with boilers, whereby the flues may be seen, and affording means whereby the same may be cleaned by steam pressure without missing any of the flues.

The invention consists of a simple and efiicient device of this nature, having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically deiined in the appended claim.

I illustrate my invention in the accompanying drawing, which with the letters of inference marked thereon, forms a part of this specification and in which I have shown an elevation of a boiler with my apparatus applied thereto.

efereuce now being had to the details of the drawings by letters:

A designates a tubular boiler` adapted to contain vertical fiues, in connection with which .my invention is to be used. A reflector consists of a base B having a hollow standard adapted to receive the Standard C, which may be held in different adjusted positions within the base by means of the collar D, which is held to the standard by means of a set screw E. The upper end of Copies of this patent may be obtained for five cents each, by

the standard is forked, as at F, the arms of the forked portion being provided with registering apertures for the reception of the screw H. A mirror, designated by letter L, is mounted in a suitable frame N, from which a lug projects downward, and which is apertured for the reception of the screw H, and affording means whereby the mirror may be held at different inclinations. A handle Q is fastened to the mirror frame and affords means of adjusting the mirror in different positions and serves as a convenient means for hanging up the mirror when not in use.

A pipe, designated by letter T, is adapted to be connected to a flexible pipe S leading from the pipe WV, through which a supply of steam may be introduced, for the purpose of cleaning .the flues.

In operation, the mirror is placed adjacent to the opening in the furnace and so adjusted that it will reflect the lower ends of the flues, in order that it may be plainly seen which 4vfiues need cleaning through the medium of the pipe T, through which steam pressure may be directed, and this accomplished without missing any of the flues, and thereby affording means for saving fuel-on account of cleaningthe boiler thoroughly.

What I claim to be new is:

A device for facilitating cleaning of boilers, consisting of a mirror having lugs extending from the back thereof, a handle pivoted between said lugs, an adjustable post having an adjustable pivotal connection with the mirror, and means for holding said post at different elevations.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

GEORGE F. KNOLLMANN.
